国内连锁经营企业物流配送模式对库存水平影响的实证研究

文章基于苏宁云商物流配送实践,根据配送网络层级、是否自营配送、配送区域、物流设施是否分品类配送、不同的零售终端数量等物流配送模式因素,设计了苏宁的八种配送情境并测算了不同物流配送情境下的库存水平,据此提出研究假设.通过收集58家国内上市连锁经营零售企业2011-2015年的经营数据,借助GMM混合回归模型,对研究假设进行验证.结果发现:国内连锁经营零售企业零售终端数量与库存周转天数负相关,每增加100个零售终端,企业库存周转天数降低0.8天左右;配送模式与库存周转天数不相关;全国型连锁经营零售企业比区域型连锁经营零售企业库存周转天数高.

An empirical study about logistics distribution mode and inventory level of chain companies in China

The paper measures the effects of eight distribution scenarios which are designed according to distribution network level, whether self-dominated distribution or not, distribution district, whether logistics facilities deliver goods by category or not and different amount of terminals on inventory levels based on the logistics distribution practice of Sunning Company, and according to the results, research hypothesis are put forward. By collecting operational date of 58 firms during period 2011-2015 and constructing GMM mixture regress model, the paper verifies the hypothesis about the effects of different logistics distribution mode on inventory levels. The results show:1) The number of the terminal has a negative correlation with inventory turnover:the inventory turnover reduces 0.8 day with the increase of every 100 stores; 2) Distribution mode has no relationship with inventory turnover; 3)The inventory turnover of national chain enterprises are higher than that of the regional chain enterprises.
